Purpose: We investigated the effect of far-infrared radiating products on cold hypersensitivity of lower limbs using CST. Methods: 7 patients with cold hypersensitivity of lower limbs were investigated in this study. Exclusive criteria was skin diseases, spinal nervous disease and external wounds. They were asked to answer the VAS of cold hypersensitivity at baseline and after 3 weeks. We measured temperature of lower limbs with Spectrum 9000 MB (Dorex Inc, USA). We performed cold stress test (CST) by 3 thermographic observation using DITI : 1st was taken after 15 minutes resting at $25^{\circ}C$, the 2nd was immediately taken after 1 minute soak in $20^{\circ}C$ water, the 3rd was taken at 15 minutes after soak. We performed 3 times of CST : 1st CST was perfomed at baseline, 2nd CST was perfomred after 1 week and just observation, 3rd CST was performed after 1 week using far-infrared radiating products (lasner, UMT, Korea). Results: After using products, temperature of foot incresed more than thigh area, but there was no significance. There was no statistical difference of VAS, change of temperature and CST between before and after using far-infrared radiating products. Conclusion: There was no statistical effect of far-infrared radiating products on change of temperature of lower limbs.

This study is designed to compare the effect of a needle with the magnet on body. We took the skin temperature of the belly with digital infrared thermographic imaging while we sticked needle and apply magnets on L14. We made experiments on 40 healthy male volunteers for one month. We classified control group not acupuncture or magnet adhering(CON). acupuncture group on left and right L14(LA). and the permanent magnet group adhering to left and right(LM). And LM is divided into S-polar permanent magnet group(LMS) and N-polar permanent magnet group adhering to left and right L14(LMN). When we observed that temperature changed with time, the skin temperature of th belly in CON descended significantly but LM, LMS and LMN is not changed significantly. As mentioned above. we observed that the needles on L14 affected the change of temperature on the belly, and conjectured that the appliance of magnets had the same results. If the mechanism depends on the meridian of body and energy. we suppose that the appliance of magnets and needles has same effects.

Objectives : We studied to discover the patterns of DITI of the patients having a both neck and upper extremity pain on one side without any nerve root compression sign and the history of cervical disc herniation. Method : We selected 26 patients as an experimental group, who had visited for a both neck and upper extremity pain on one side without any nerve root compression sign, at the department of acupunture and moxibustion in Conmaul oriental medical hospital, during 2001. 01. - 2003. 09. And 31 normal adults were selected as a control group, not having any neck or arm pain and any history of cervical disease. We analyzed the segmental temperature statistically with t-test. Results & Conclusion : There was a significant change of temperatures in the scapula, posterior brachium, lateral forearm and dorsal hand area. And the experimental group showed cold spot and disruption of normal thermographic shape that were usually shown on the cervical sprain.

Purpose: This study was performed to evaluate DITI (Digital Infrared Thermographic Imaging)'s potential for diagnosis and indicator of abdominal cold hypersensitivity treatment from the clinical case study. Methods: The patient was a 35-year-old woman who was suffered by general coldness, sweating and general pain. The patient was treated by Herb medicine, Acupuncture treatment, Moxa treatment and Physical Treatment. The progress of symptoms was evaluated by checking the change of VAS, and inspecting the DITI. We studied the statistical significance from the difference of DITI results before and after treatment by paired T-test using SPSS windows (version 12.0). Results: The general coldness, sweating and general pain of this patient have declined, especially the abdominal coldness improvement showing. As a results, the temperature of four abdominal sites(GV4,6,12,17) after treatment were statistically higher than those before treatment. With comparison of Indang, DITI difference of abdominal sites before and after treatment were statistically significant from paired T-tests. Conclusion: The results suggest that DITI can be used for the diagnosis and assessment of abdominal cold hypersensitivity treatment.

Objectives : The aim of this study is to validate the correlation between Assessment Instruments of Knee OA and digital infrared thermographic imaging(DITI) and to find out the methods to assess knee OA by DITI. Methods : 60 subjects were evaluated. They were asked to answer VAS pain scale, WOMAC, KHAQ and LFI. Correlation was assessed by examining the spearman's rank correlation coefficients. Results : VAS, WOMAC and LFI was correlated with not only the thermal difference between Ant. knee and Post. knee, but also the lowest temperature of Ant. knee. Conclusion: DITI value was useful for evaluating the degree of OA. And we should find out that decrease of pain is correlated with change of DITI value.

Thermal deformation, such as bending and twisting, occurs among the polymer parts of air-conditioner indoor units because of repetitive temperature change during heating operation. In this study, a numerical method employing finite-element analysis to efficiently simulate the thermal deformation of an assembly is proposed. Firstly, the displacement of an actual assembly produced by thermal deformation was measured using a 3D optical measurement system. The measurement results indicated a general downward sag of the assembly, and the maximum displacement value was approximately 1 mm. The temperature distribution was measured using a thermographic camera, and the results were used as initial-temperature boundary conditions to perform temperature-displacement analysis. The simulation results agreed well with the measured data. To reduce the thermal deformation, the stiffness increased 100%. As the results, the maximum displacement decreased by approximately 5.4% and the twisting deformation of the holder improved significantly.

Purpose : The purpose of this study is to report the effect of Traditional Korean Medicine(TKM) on amenorrhea which oligomenorrhea has become worse. and to investigate the change of body temperature measured by Digital Infrared Thermographic Imaging(DITI). Methods : The patient in this case was 29-year-old female. The chief complain was amenorrhea which oligomenorrhea has become worse. We treated her by TKM. and evaluated the progress of symptoms by DITI. And then We compared DITI before treatment and after treatment. Results :After TKM treatment. the differences of temperature between Indang(印堂) and the four abdominal sites(CV4,6,12,17) were decreased on DITI. respectively. Conclusion : TKM treatment is effective on amenorrhea which oligomenorrhea has become worse. And DITI could be useful to assess the amenorrhea objectively. But more research should be needed.

Purpose; The purpose of this study is to objectively identify and quantify the wearer's feelings of wearing glasses. Methods: The temperature of the skin on the nose ridges and ear, and the area where the glasses were seated, was measured using a thermal imaging camera. Results: Before wearing the glasses, the temperature of the skin surface on the nasal ridge was 34.908 ± 0.875 ℃ and the temperature of the ear region was determined as 31.981 ± 0.549 ℃. The changed temperature measured at 5 minutes later after taking off the glasses showed that the nasal ridge was determined as 35.467 ± 0.342 ℃ and the ear area was determined as 32.994 ± 0.412 ℃ (p<0.05). Conclusions: In this experiment, it was revealed that the glasses cause discomfort and heat in the fitting area. It was the first attempt to study objectively and scientifically. Analysis of frame fitting points by using thermal camera is expected to be helpful when consulting a sensitive person about changes in the fit of glasses.
